I'd do some heard research before asking a lot of those questions. NALP answers almost all your questions about billables, and some firms may include some of those answers on their websites (especially if this is a summer program re: how work is assigned, etc.).

Typically, if it's a callback sort of situation, I usually ask "personal" questions about the interviewer's experiences in the firm, why they like it there or chose this firm, what kind of training opportunities they've had, etc. If I'm interviewing with a partner or senior associate who has been with the firm for a good number of years, I occasionally asked about how the firm's grown in the last 5 years, how that person's practice has evolved (esp if it's a practice area I'm interested in), and where the person thinks the firm may be heading in terms of growth strategy.

My ultimate goal with questions was to *never* ask a question that is clearly answered somewhere easily accessible, to tap into the interviewer's personal experiences/opinions (which also shows that you are interested in the person you're speaking to, something that everyone typically appreciates), and to try to get a sense of what the firm is like and where the firm is going.

I think it's important to ask questions that show that you know something about the firm and have a sincere interest.

For example, if the firm has program XYZ for new associates, ask an intelligent question about that program. I also second jacy in recommending asking more personal questions. I think it often helps build repor if done right.

*In clinical studies, Matthies was well tolerated, but women who are pregnant, nursing or might become pregnant should not take or handle Matthies due to a rare, but serious side effect called him having to make child support payments.

Ask them any question that will give them an open door to talk about themselves for a seemingly endless duration. Lawyers like to talk.

"What are some of the cases you're currently working on?" is always a good one b/c it gives you an opportunity to display that you can be conversant on legal issues. I find that this question usually leads to a good discussion... unless the cases they're working on are boring as hell. But hey, if that's true then you probably don't want to work there.
